Yangtze River Three Gorges Project is the world’s largest water conservancy and hydropower project across the century. It has a grand scale and attracts worldwide attention. The Three Gorges Project not only has significant economic benefits, but also has significant environmental benefits and social benefits. It is one of the major projects to achieve the long-term goal of China’s social and economic development. After the completion of the Three Gorges Project, a large reservoir of 39.3 billion cubic meters of storage capacity can be formed, of which flood control storage capacity is 22.15 billion cubic meters. By adjusting the flood peak of the Three Gorges Reservoir and intercepting floods, flood control standards at the Jingjiang reach of the Yangtze River will be raised from once every 10 years to once every 100 years,
